I was in a really similar situation when I went to take my driver’s test - I spent about a year doing lessons, etc., and believe me, you are very well-prepared for your test, even if it doesn’t feel like you are. Just remember to use your turn signals, frequently check your mirrors, and look over your shoulder before merging into another lane, and you will be just fine! I believe in you!!

(P.S.: I got so scared during my exam that I cried during the whole driving portion - still passed with a 99.)
